Answer:
The phenotype ratio of HhGg x HHGg is 9:3:3:1.
Explanation:
The phenotypic ratio is concerned with the relative number of the offspring man manifesting a particular trait or combination of traits. It can be determined by making test cross and then finding the frequency of the traits.
phenotype ratio of HhGg HHGg is a different di-hybrid cross. One 'g' will be combined with the one 'h'. In result the huge will be dominant that of small and green will be dominant to that of blue.
HhGg × HhGg ( huge/green × huge/green)
From the below stated table we can conclude the ratio which is like huge/green =9,
Small/green = 3,
huge/blue=3,
small/blue = 1.
Hence it is proved that the phenotypic ratio will be 9:3:3:1.
<h2>Answer:</h2>
The correct answer is option A which is in prokaryotes photosynthesis takes place on the folds and in eukorytes, it is present in specialized organelles.
<h3>Explanation:</h3>
- Prokaryotic cells don't have distant nucleus and specialized organelles. in photosynthesizing prokaryotes, Photosynthesis takes place on the system of folded membranes near the cell membrane known as mesosomes.
- While eukaryotes, all organelles are fully specialized and chloroplasts are double membrane organelle for photosynthesis.
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
Some molecules are too big they cannot diffuse through the membrane, for example starch (glucose) molecules.
